A $17 Million Lesson in Waiting Too Long
Anne Milner Fields inherited an oil business from her husband in the 1960s and spent decades building it into a family fortune. When she died in June 2016, a family limited partnership her attorney had created for her roughly a month earlier was supposed to shield close to $17 million of that fortune from estate tax through valuation discounts. Instead, in June 2026 the Fifth Circuit Court of Appeals affirmed a Tax Court ruling that the entire amount belonged back in her taxable estate — plus a 20% accuracy-related penalty on top of the resulting $1.8 million tax deficiency.
The case, Estate of Fields v. Commissioner, is the latest in a long line of failed family-limited-partnership (FLP) strategies, and it lands at a moment when the stakes for getting succession planning right have never been higher. The One Big Beautiful Bill Act made the $15 million federal estate and gift tax exemption permanent starting in 2026, which has pushed many business owners to revisit their transfer plans. Fields is a cautionary tale about exactly how not to do it — and a useful blueprint for any owner who actually wants their plan to hold up.
What Actually Happened in the Fields Case
Fields suffered from end-stage Alzheimer's disease and was hospitalized repeatedly in the final months of her life. Acting under a power of attorney, her son implemented an estate plan that moved roughly $17 million in assets — the bulk of her wealth — into a newly formed family limited partnership about a month before she died. An appraiser then applied a 36.25% aggregate discount for lack of control and lack of marketability, valuing the contributed interest at around $10.8 million for estate tax purposes on the date of death.
The IRS challenged the arrangement, and the paper trail didn't help the estate's case. Communications between the estate-planning attorney and the appraiser reportedly discussed getting "a deeper discount" on the valuation — language that reads far more like tax engineering than legitimate business restructuring.
The Tax Court sided with the IRS in 2024, and the Fifth Circuit affirmed that decision in June 2026. The court's reasoning centered on Internal Revenue Code Section 2036(a), which pulls certain lifetime transfers back into a decedent's taxable estate unless the transfer qualifies as a "bona fide sale for adequate and full consideration." To claim that exception, an estate has to show the transfer served a substantial non-tax purpose — not just a plausible-sounding one invented after the fact.
The court found the estate's justifications to be, in its words, "post hoc theoretical justification" rather than the actual motivation behind the transfer. Given Fields's age, her declining health, and the timing of the transfer just weeks before death, the court concluded the real purpose was estate tax avoidance. That finding wiped out the valuation discount entirely and triggered the 20% penalty for good measure.
Why the Bona Fide Sale Exception Is So Hard to Win
Family limited partnerships aren't illegal, and valuation discounts for lack of control and marketability are a well-established, entirely legitimate planning tool — when the facts support them. The problem in Fields, and in the string of similar cases before it (Strangi, Bongard, and others), is that courts have grown skeptical of FLPs assembled at the eleventh hour with no operating history and no genuine business rationale.
Based on how courts have analyzed the bona fide sale exception in Fields and earlier cases, a few fact patterns consistently sink an FLP:
- Deathbed timing. Forming the partnership and funding it weeks or months before death, especially once the transferor's health has already declined, signals that estate tax avoidance — not business planning — was the point.
- Concentrated transfers. Moving the overwhelming majority of a person's net worth into a single new entity looks less like diversification or management efficiency and more like a wrapper built solely to generate a discount.
- No participation by the transferor. When the person contributing the assets lacks the capacity to actually manage or oversee the partnership (as Fields did, given her Alzheimer's diagnosis), it undercuts any claim of ongoing business purpose.
- A damaging paper trail. Emails or notes that talk about "maximizing" or "deepening" a discount — rather than documenting a legitimate operating rationale — are exactly what the IRS looks for and exactly what courts cite when they rule against the estate.
- Post hoc justifications. Business purposes that show up for the first time in litigation, rather than in contemporaneous planning documents, rarely persuade a court.
None of this means FLPs don't work. It means they only work when they're built years in advance, funded with a genuine operating purpose, and run like an actual business — not assembled as a last-minute tax maneuver.
The Broader Succession Planning Problem This Case Exposes
Fields is a dramatic example of a much more common failure: business owners waiting too long to plan for what happens to their company and their wealth. The numbers on this are sobering. Survey data compiled by Nationwide and others shows that roughly three out of five small business owners have no plan at all for what happens to their business when they're ready to step back, and nearly two-thirds of family-owned businesses have no documented or communicated succession plan. According to SBA figures, only about 30% of family businesses survive into the second generation, 12% into the third, and just 3% make it to a fourth generation or beyond.
The reasons owners give for not planning track closely with what went wrong in Fields: nearly half think it isn't necessary yet, roughly a third aren't sure when to start or whom to call, and a meaningful share simply don't want to confront handing over what they built. That reluctance is understandable — but it's also precisely what turns a routine estate transition into a forced, rushed, deathbed-style transfer that a court is primed to view with suspicion.
The lesson generalizes well beyond FLPs. Any transfer strategy — gifting a stake in the business to children, setting up a trust, restructuring ownership ahead of a sale — carries more legal and financial risk the closer it's implemented to a health crisis or a death. Advance planning isn't just good practice; in the eyes of the IRS and the courts, it's often the entire difference between a strategy that holds up and one that gets unwound with penalties attached.
What Business Owners Should Actually Do Differently
If there's a practical takeaway from Fields, it's that the "how" and "when" of a succession or estate strategy matter as much as the strategy itself.
- Start the conversation now, not at a health scare. Succession planning done while an owner is healthy and actively involved in the business looks — and legally is — fundamentally different from planning done in a hospital room.
- Give any entity real time to operate before it matters for tax purposes. An FLP, holding company, or trust that has existed and functioned for years carries far more credibility than one formed the same month as a terminal diagnosis.
- Document the actual business reason, before you need it. Write down the operational rationale — consolidating scattered assets, protecting a business from a spendthrift heir, easing management succession — at the time you create the structure, not in a memo prepared for litigation years later.
- Keep the transferor involved. If the whole point of a partnership is that family members manage assets together, make sure the transferring owner can meaningfully participate, not just sign paperwork under a power of attorney.
- Watch what you put in writing. Advisors and appraisers should be documenting valuation methodology and business judgment — not chasing "a bigger discount" in emails that will surface in discovery if the IRS ever audits the return.
- Loop in your bookkeeper or accountant early. The financial records supporting a valuation discount — asset values, cash flow history, ownership structure — need to be clean and well-organized long before an appraiser or the IRS ever looks at them.
